W_L, there seems to be some cultural differences here, if you see a problem and he doesn't. Maybe you have to show him, but do it nicely. What I mean by this is start asking him to do things you want to do, even though it may not be his cup of tea. If he refuses and suggests something he likes instead, then you state firmly that you're not interested in doing that. After a few times of wanting to move in different directions, he'll probably get the hint that this isn't going to work out. When he does, you can both agree to break it off amicably. I hope that helps.
